acter comprising novel means whereby the clamp- I ing elements may beretained ininoperative position to facilitate insertion of the endportion of the cable or guy wire.

Another very importantobjcct of the invention is to provide a guy wirefastener ofl the character described embodying a construction andarrangement which is such that the device may be expeditiouslyassembled.

Other objects of the invention are to provide a guy wire fastener of thecharacter set forth which will be comparatively simple in construction,strong, durable, highly efficient and reliable in use, compact and whichmay be manufactured at low cost.

All of the foregoing and still further objects and advantages of theinvention will become apparent from a study of the followingspecication, taken `in connection with the accompanying drawings whereinlike characters of reference designate corresponding parts throughoutthe several views, and wherein:

Figure 1 is a vertical sectional view through a guy wire fastenerconstructed in accordance with the present invention.

Figure 2 is a view in side elevation thereof.

Figure 3 is an elevational view, taken at right angles to Fig. 2.

Figure 4 is a View in horizontal section, taken substantially on theline 44 of Fig. 2.

Figure 5 is a vertical sectional view substantially similar to Fig. 1but showing the clamping rollers retained in inoperative position.

Figure 6 is a vertical sectional view, taken substantially on the line6-6 of Fig. 5 with the cable or guy wire omitted.

Figure '7 is a detail View in perspective of one of the pivot pins.

Figure 8 is a perspective view, showing a slight modification.

Referring now to the drawings in detail, it will be seen that thereference numeral l designates a substantially ovate plate of suitablemetal having formed in its edge or periphery a spirally ribbed groove 2for the reception of an end portion of a guy wire, as at 3. Also formedin the plate l is a. vertical slot 4. The reference numeral 5 designatesa pair` of recesseswhich are formed in the periphery ofthe plate I Vatintermediate points. H

Mounted adjacent the upper portion of the platel and movableverticallyindependently of 5 said plate `is a pair of horizontal metallic bars 6.Connecting the pair of bars 6 and extending therethrough and therebeyondis a pair` of pins 'I. Peripherally grooved clamping rollers 8 arejournalled on the pins 'I between the bars 6.

Journalled onthe-projecting end portions of the pins 1 and dependingtherefrom are pairs of slotted metallic links 9. `Extending between thelower endportions ofthe pairs of links 9 `are pins II). -Journalled onthe pins I0 between the l5 lower portions of the links 9 arecomparatively large, peripherally grooved clamping rollers Il.

The reference numeral I2 designates pairs of metallic links having oneend portion journalled on the pins IIJ between the rollers II and the 20lower end portions of the links 9. The other end portions of the linksI2 are journalled on a pin I3 which is operable vertically in the slot 4in the plate I.

The pins 1, I0 and I3 are substantially similar in construction.Referring to Fig. 7 of the drawings, it will be observed that the pinI3includes reduced end portions or necks I4 terminating in heads I5.Mounted on the end portions of the pin I3 is a clevis I6. The clevis I6has formed in its end portions keyhole slots I'I for the reception ofthe reduced end portions I4 of the pin I3. 'Ihe reference numeral I8designates a bar which is insertable in the lower portions of thekeyhole slots I1 and the slot 4 foi` engagement beneath the lower endportions of the links I2 for holding the clamping rollers 8 and Il `inraised or inoperative position when desired.

It is thought that the manner in which the device functions will bereadily apparent from a consideration of the foregoing. As shown toadvantage in Figs. 5 and 6 of the drawings, the bar I8 is insertedthrough the lower portions of the slots I'I and 4 for retaining theclamping rollers 8 and II in raised position. The end portion of the guywire 3 may then be conveniently inserted in the device, said guy wiretraversing the arcuate recesses 5. The bar I 8 is then removed and whena pulling force is exerted on the clevis I6 the guy wire is firmlyclamped between the plate I and the rollers 8 and II. The constructionand arrangement is such that the greater the pull to which the device issubjected, the greater will be the clamping action on the guy wire.

The keyhole slots l1 permit the clevis I 6 to be expeditiously removedor detached when desired. In Fig. 8 of the drawings, the referencenumeral i 9 designates a cable which maybe connected to the fastener inlieu of the clevis I6. Toward this end, the cable I9 has secured on itsend portions a pair of ears or the like 20 having formed therein keyholeslots 2| for the reception of the end portions of the pin I3. Thisarrangement may be1 used for connection with a pole, also forconnectinginsuliators,ifdesired.

It is believed that the many advantages of a guy wire fastenerconstructed in accordance with the present invention will be readilyunderstood and although preferred embodiments of the de'- vice are asillustrated and described', it is tobe understood that furthermodifications changes in the details of construction may be re;-

sorted to which will fall within the scope, of the` invention asclaimed.

What isi claimed isf;

l. A guy' wireI fastener comprising a substantially ovate plate having aperipheral groove therein for the reception of. an end portion of awire, said.' plate further' having a vertical slot therein,- a pairr ofbars extending horizontally adjacentthe` small end portion of saidsubstantially ovate plate andi movable. relative thereto. cfa-mping'rollers journaled' between said bars, pairs of' links pivot'a-Hyconnected to the bars; clamping roliersjourrraledbetween said Iinks,'thefirst` and second' named rollers being cooperable with the plate forclamping the guy wire therebetween', links pivotallyA connected to thefirst named links, a pin' pivotal'ly connecting the second' narnedlinksat one end, said pin being operand' able in the slot in the plate, aclevis mounted on the pin and having keyhole slots in its end portionsfor the reception of said pin, the pin comprising heads on its ends, anda bar engageable in the slots beneath the second named links for holdingthe rollers in inoperative position.

2. A guy wire fastener of the class described comprising a substantiallyovate plate having a slot therein, a pin operable in the slot, said pinincludingI reduced, end portions terminating in heads', a clevislmounted on the pin and' having keyhole slots in its end portions for thereception of the reduced end portions of the pin, links pivotallyconnected to the pin, rollers journalled on said li-nks and cooperablewith the plate for clampingv aguy Wire therebetween, and a memberengageabl'e in the lower portions of the slots beneath. the; links forlholding the rollers in inoperative position.

3. A guy Wire fastener comprising a substantially ovate, platezhaving `aslot therein, a pin operable; in the slot, said. pint includingv reducedend portions--terminating in.r heads projecting beyond'. the. sides ofthe plate, pairs of links pivotallyconneeted to the pim. rollersjournalled between. the pairsof links, said rollers, in conjunction withthe plate; constituting meansA for clamp--v ing an! end portion of aguyWire, aconnector adapted to be detachably coupled to the pin, saidconnector having keyhole slots in its end porc tions for the receptionof the reduced end prtions of the pin, and a member engageable in thelower portions of the slots beneath the links for holding' the rollersin inoperative position.
